adding custom categories to a cpt-onomy

Hi there,

so I think I’ve understood the basic principles behind this plugin and it seems like it’s the thing that help me solve a problem I’ve had for long. But there is a catch;

I need the following functionality;

I have created a cpt-onomy and appended it to posts. Now I need that cpt-onomy to work like posts, with their own categories and permalink structure, as well as archive pages.

I can work out the latter two, but how do I add a category (not append already existing categories to it) to my newly created cpt-onomy?

I though of solving this making the cpt-onomy hierarchical, but that could cause some problems in the editing page when there is more than several hundred items, each with custom parent-child relationship.

help please!
